Teho produces Malbec from Mendoza, Argentina's premier wine region. The winery's portfolio centers on this signature varietal, which thrives in Mendoza's high-altitude terroir and continental climate. The Tomal Vineyard Malbec and its flagship Malbec both achieve ratings of 92.7 from prestige critics including Decanter, Wine Enthusiast, Wine Advocate, and Wine Spectator. The Tomal Vineyard El Corte, a Malbec and Cabernet Sauvignon blend, rounds out the core range at 92.1. Mendoza's volcanic soils and diurnal temperature swings produce Malbecs of depth and structure—dark fruit, firm tannins, and aging potential are hallmarks of the region's expression of this varietal. Teho's wines reflect this character.
